BUILT-UP LADLE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed May 6, 1910. Serial No. 559,705.

.To oZZ whom it may concern:

Be it known that I, MUNsoN H. TREAD- WELL, a citizen of the UnitedStates, residing at New York, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Built- UpLadles, of which the following is a full, clear, and exactspecification.

This invention relates to built up ladles, and more particularly hasreference to what are commonly termed cinder ladles,7 that is ladlesused for carrying away slag, etc. from blast furnaces, or foundries.Such ladles are commonly made of cast iron, and are not ordinarily linedwith refractory material, and consequently are subject to burning outand other accidents. Where a ladle is cast in one piece, and especiallya ladle of large capacity, when a burn out occurs the ladle is uselessand must eventually be scrapped, as the value of the metal isconsiderable. In order to utilize the metal such a casting must bebroken up, which has been found difficult and expensive in the case oflarge and heavy cast ladles.

The object of this invention is to provide a ladle which can beconstructed of rolled plates, preferably steel, and unlined, which canbe riveted together and cut up when necessary to be scrapped, withinconsiderable expense. The invention, furthermore enables small holesto be patched, or to have parts renewed, without destroying theusefulness of the entire ladle.

A further object of the invention is to provide improved supportingmeans for a built up ladle.

The invention will be more fully understood in connection with theaccompanying drawing, wherein Figure l is an elevation partly in sectionof a ladle embodying the invention, and Fig. 2 is a top plan view.

In building up a ladle of plates, it is essential that the interior besmooth and free from projections or interstices in which the skull canbind and thereby prevent discharge of the entire contents. In order toaccomplish this, the ladle embodying my invention is constructed of anumber of rolled segmental plates 1 having their edges closely abuttingand fastened together by external lapping plates 2, riveted together byrivets 3, having their heads interiorly countersunk as at 4 in Fig.- 2.Thereby, is formed an annular conical shaped body open at top andbottom, which is strengthened by intermediate hoops 5 riveted to thesegmental plates between the lapping plates 2, and to which are attachedhoop members 6 overlying the lapping plates 2 and connected to the hoops5. 7 are bumping plates, preferably carried by the lapping plates 2above the hoop members 6 to take the shock when the ladle is mounted ona dumping car according to the known practice. At the top, above theends of the lapping plates 2, is externally fastened a top hoop or rim9, preferably consisting of an angle bar bent and rolled to propershape, forming a strong and at the same time light rim. At the bottom isfastened a second angle plate 11 having its flange turned outwardly andslightly downwardly. l2 represents a bottom which may be a casting,forging or plate having a flange 13 through which and the flange 11 andfastening bolts 14 are passed, securing the bottom to the body. Theinterior edge of the bottom is made to fit the bottom of the body 1, sothat no spaces or interstices are formed in which the skull can takehold. In order to mount the ladle on a cinder car, it is provided withfeet 16, which may be castings adapted to rest on a bail or yoke 17, andriveted to the body plates 1, preferably. The feet 16 are recessed totit the hoops 5 above and below, and riveted to the body plates 1 asshown, and thereby a firm support secured, it being seen that should theplates 1 become red hot the hoops 5 would still carry the strain fromthe feet and thereby the whole weight is not directly supported by thebody plates 1.

From the foregoing description, it is thought the advantages of theinvention will be understood, and it will be seen that by the inventionis provided a built up plate cinder ladle which can be cheaply andeconomically built in large sizes and readily cut apart when worn out.

Various changes in the details andV specific construction herein shownmay be made without departing from the scope of the invention.

Having thus described my invention, I declare that what I claim as newand desire to secure by Letters Patent, is`

1. A built up cinder ladle comprising segmental plate sections havingtheir edges abutting to form a conical body having a smooth interior,outside lapping plates secured to said abutting sections, an externalhoop carried by said body adjacent the lower end, and a bottom separablyattached to said hoop.

2. A built up cinder ladle comprising segmental plate sections havingtheirV edges abutting to form a conical body having a smooth interior,outside lapping plates secured to said abutting sections, a flangedstrip hoop secured to said plates around the top and bottom edges ofsaid body, and a bottom section separably secured to the flange of saidbottom hoop.

3. A built up cinder'ladle comprising a conical body formed of segmentalplate sections secured together by longitudinal outside lapping plates,a flanged hoop secured around the bottom portion, and a bottom sectionseparably carried by said hoop.

4. A built up cinder ladle comprising a conical body formed of segmentalplate sections secured together by longitudinal outside lapping plates,an intermediate plate hoop secured to said sections, a bottom section,and supporting feet secured to certain of said sections and braced bysaid hoop.

5. A built up cinder ladle comprising a conical body formed of segmentalplate sections secured together by longitudinal outside lapping plates,an intermediate plate hoop secured to said sections, supporting feetadjacent said hoop, a flanged bottom hoop, and a bottom section carriedby said flanged hoop.

In testimony whereof I aiiiX my signature, in presence of two witnesses.
